Title: Improvements in or relating to Firing Mechanism for Automatic Machine Guns.
IPC: F41A5/18
Filed: 1917-12-20
Abstract: 130,021. Birmingham Small Arms Co., and Norman, G. Dec. 20, 1917. Fire between aircraft propeller blades, controlling and synchronizing.-Relates to means for synchronizing the firing of an automatic machine gun with the movements of an external member, e.g. the propeller of an aeroplane so that each discharge can only take place, between the blades of the propeller. According to the invention, a machine gun, of the kind wherein the striker spring is interposed between the striker and a breech-bolt actuating-member, is provided with (1) a spring-operated catch engaging a fixed part of the gun to retain the breech-actuating member in the firing position, the catch being released when the actuating member is moved backward either by hand or automatically, and its spring exerting a pressure on the actuating member opposed to the pressure of the striker spring, and (2) a device on the actuating member interposed, when the breech is closed, between the sear and a trigger device under the control of the external member with which the firing is to be synchronized. Fig. 1 shows the invention applied to a Lewis gun, the trigger device 26 of which is under the control of the engine of an aeroplane. The striker pin 35 slidably mounted in the breechbolt actuating member 2 is moved into cocking position, with the vertically-sliding sear 28 in engagement with the bent 34, when the member 2 moves rearwards, and the spring 15 is stressed by the return movement of the member. Within the hollow rear portion 1 of the member 2 is mounted a catch 3 under the control of a spring 13 which acts through a thimble 14 on a projection 12 above the pivot 5 to move the rear nose 6 downwards into engagement with a recess 8 in the fixed casing 9 when the breech is closed. When the breech is opened by hand through the cocking lever 17, or automatically the catch 3 is lifted after a certain interval by an incline 10 on the member 2. The spring 13 exerts a forward pressure on the member 2 to neutralize the rearward pressure on the spring 15. Within the rear hollow portion 1 is also mounted an interposer device 19 having a pivotal movement about pin 20 and also a limited longitudinal movement provided for by a slot 21, both movements being controlled by a spring 29. The spring controlled trigger plunger 26 on the gun is reciprocated from the aeroplane engine by a rod 32 and acts through the device 19 to lift the sear when the breech is closed. In the event of the trigger plunger 26 being raised in advance of the return movement of the member 2, the trigger 26 engages in front of a projection 23 on the device 19 and holds up the device 19 so that firing can only occur on the next upward movement of the plunger 26.

Abstract: 892,863. Electric selective signalling systems. BUSH & RANK CINTEL Ltd. June 7, 1960 [June 4, 1959], No. 19112/59. Class 40 (1). Counter read-out is obtained by moving a member to one of a plurality of predetermined positions in accordance with the state of count in order to vary the amount of radiation incident on one or more of a plurality of radiationsensitive devices each of which provides a signal on one of a plurality of output channels representative of the state of count. In the embodiments described the movable member is the pointer of a meter which interrupts or reflects light on to selected photo-cells. The input to the meter is obtained from a resistance network coupled to the counter. The photo-cells may be arranged in a row, each cell corresponding to a possible position of the pointer, one of a number of output leads being selected for each position. As shown in Fig. 4, a ten-state input to the meter may be converted to a four-digit binary-coded representation, a group 25 of cells 22 being provided for each position of pointer 27. A scale of 16 input to the meter may be converted to a scale of 10 output by employing 15 cells (no cell for zero position), some of which are connected in pairs to give 10 separate output channels. Alternatively, only 9 cells 33, Fig. 6, may be used, each cell in the top row being selected in two adjacent positions of the pointer. Specifications 572,884 and 799,825 are referred to.

Title: Improvements in electric selectors
IPC: H01H67/02
Filed: 1935-07-05
Abstract: 459,299. Electromagnetic switches; actuation of switches. TELEFONAKTIEBOLAGET L. M. ERICSSON, 18, Dobelnsgatan, Stockhohn. July 5, 1935, No. 19282. Convention date, July 6, 1934. [Class 38 (v)] [See also Group XXXIX] In a selector switch of the type in which normally adjacent contact springs are selectively actuated, the reciprocating movement of a manually or electromagnetically operated driving member in co - operation with a guide member causes a contact actuating member such as a ball or roller to be advanced step-by-step from one set of contacts to the next and to be forced by the guide at each step into a position for actuating the selected contacts. In the selector shown in Figs. 1, 2 and 4, the armature of a magnet 2 carries a pair of combs 5, 6 having teeth 71, 7<11>. At each release of the armature a ball 21 is forced upward by one of the comb teeth, actuating a set of contact springs by engagement with a spring 13 or 15, and being caused by the spring and by the slope of the comb tooth to move against the side of the next tooth. When the armature is re-operated, the spring and the slope of the tooth 10<1> of a fixed toothed member co-operating with the comb cause the ball to move on to the next comb tooth and against the side of the next fixed tooth. Alternatively, the springs can be actuated on the energization of the magnet. When the ball reaches the limit of its travel along the comb 5 it travels back along the comb 6, actuating further sets of springs in turn. Modified constructions are referred to in which the ball is restored step-by-step without actuating contact springs, in which it is simply allowed to roll back to its starting position, in which two balls are stepped simultaneously, being arranged so that one is selecting while the other is being restored or so that both select simultaneously. A further modification comprises a tube full of balls and into which the selecting ball is forced at the end of its travel, a ball from the other end then being forced into the selecting path. A circuit may be made by the ball itself. In further modifications, the ball is replaced by a roller &c. In another arrangement, Figs. 6 to 8, a contact selecting bar 30 or a spindle 29 is given a step-by-step rotary movement by a pair of fixed toothed guides 25, 26 when the spindle is reciprocated. The bar may act as a contact-making as well as a contact-actuating member. The Specification as open to inspection under Sect. 91 comprises also the following arrangements which, however, are not described in detail: (1) the actuating member may be restored along the path over which it was set, actuating the swing contact springs during its restoring movement; (2) two selecting mechanisms may be employed for actuating a spring set at the intersection of horizontal and vertical bars ; (3) another kind of co-ordinate selector comprises a selecting mechanism of the kind described for selecting for actuation one of a number of similar mechanisms. This subjectmatter does not appear in the Specification as accepted.

Abstract: 145,999. Norton, J. B., and Norton, H. Aug. 16, 1919. Driving - gear for winding and paying- out apparatus; selfsustaining gear. - In hoisting - apparatus, a roller D mounted in the member B of a clutch bears against a cam path on the driving shaft A. A second roller E mounted in the same clutch member moves in a cam slot F formed in a casing which cannot move longitudinally, and is prevented from rotating when the spring-pressed pin G engages one of a series of holes in the fixed plate H. The pin G is connected to levers L which project into the slot F. A clutch member J is keyed to the gear case and bears against a shoulder on a shaft which is integral with the clutch member B. Clutch members C, K on the driving-gear are engaged by the clutch members B, J, respectively, one clutch being engaged when the other is disengaged. When the shaft A is rotated in either direction, it drives the clutch member B as soon as the roller D reaches the end of the cam-path. The rotation of the member B carries the roller E along the slot F, thereby releasing the pin G and engaging the clutch members B, C. At the same time the clutch members J, K are disengaged, and the hoisting- mechanism is rotated. Should the load overcome the driving effort, the roller E is moved along the cam-slot, the clutch members B, C are disengaged, the casing is locked to the plate H by the pin G, and the clutch member B is disconnected from the driving-shaft. At the same time the clutch members K, J are engaged, and further movement of the load is prevented.

Abstract: 946,210. Gas-blast circuit-breakers. A. REYROLLE & CO. Ltd. June 3, 1960 [June 5, 1959], No. 19375/59. Heading H2B. In a gas-blast circuit-breaker an inlet-blast valve 16, a moving contact 24 and an exhaust valve are coupled together for co-ordinated operation by a common operating means, the inlet valve being opened to admit compressed gas, the contacts being separated and the exhaust valve then being closed to maintain pressure in the arcing chamber 10. When the circuit-breaker shown is to be opened, compressed air is admitted from a receiver 13 to the lower end of a cylinder 33 on the operation of a control valve 35. The compressed air forces up a combined operating piston and exhaust valve member 32 secured to an operating rod 25 carrying the movable contact 24 and the inletblast valve 16. This opens valve 16 to admit the gas-blast from a receiver 14, then the moving contact 24 is separated from the fixed contacts 23 and the arcs drawn are blown by the gasblast through nozzles 29 on to arcing electrodes 30 and extinguished. The blast exhausts through vents 37 until the vents are closed by the piston 32 engaging an annular seating 36.
